Abstract

For more than ten years, a collaboration of European scientists has been producingsimulations of the Gaia mission. These simulations range from detailed realistic simulatedCCD images to large volume simulations of the Gaia telemetry.

The data of this decade of simulations has been used for many purposes: instrumentdesign, data processing software testing and validation, prediction of missionperformances, etc. Today the launch date is getting closer and the task of the simulatorin the mission preparation will be wrapped up in a couple of years.

However, this is not the end of the story since the Gaia simulator can also be used forthe preparation of the scientific exploitation of the Gaia data. In this talk we willpresent the simulator and its components, the data it can produce and the perspectives forthe utilisation of this data during the mission, both for data evaluation and scientificexploitation.
